METHOD OF PRODUCING S-PENTYLCARBOTHIOL-1aH,2'H-[1,2]PYRAZOLINO[3',4':1,9](C-I)-[5,6]FULLERENE Russian patent published in 2014 - IPC C07D231/54

Abstract RU 2517169 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing sulphur-containing fullerene derivatives and specifically to a method of producing S-pentylcarbothio-1aH,2'H-[1,2]pyrazolino[3',4':1,9](C₆₀-I_h)-[5,6]fullerene of formula (1), which can be used as effective nano-component additives for industrial oil, as well as a novel material for optoelectronics. The method involves reacting C₆₀-fullerene with pentyldiazothioate of formula N₂CHC(O)SC₅H₁₁ in o-dichlorobenzene in molar ratio C₆₀:diazothioate=0.01:(0.02-0.05), preferably 0.01:0.03 at 40°C for 0.5-1.5 hours.

EFFECT: method enables selective production of S-pentylcarbothio-1aH,2'H-[1,2]pyrazolino[3',4':1,9](C₆₀-I_h)-[5,6]fullerene with output of 41-58% .
